Following [1]}, we report video-level AUC score and pAUC [2]} score
by respectively averaging the AUC scores and pAUC scores of each frame in a video.
pAUC is a global metric at a low false alarm rate. Given the significant class imbalance in the real world,
pAUC can better reflect the performance of methods in the real world.
To facilitate comparison with other methods, we also report the accuracy score.
Besides, some visualizations (t-SNE [3]}) are also reported to further evaluate the performance.
